摘要
"EAST(超导托卡马克核聚变实验装置)"中的快控电源是一种大容量单相逆变电源,其为真空室内部的反馈线圈进行快速励磁以抑制等离子体的快速垂直漂移。为满足其大电流快速响应要求,采用多组逆变单元串联均流电抗器并联运行。文中根据EAST快控电源系统的设计要求,对逆变单元采用电流闭环调节控制,可有效提高系统对低频和直流环流的抑制能力。实验结果说明该系统设计方案合理,控制策略有效。
The fast control power supply in EAST（Experimental Advanced Superconducting Tokamak） is a kind of large capacity single phase inverter,which excites feedback coils to produce magnetic field to restrain plasma＇s fast vertical displacement.The method of multiple inverters paralleled with current sharing reactor is presented to meet the need of large current and fast control.According to the design demand of EAST fast control power supply,the adjuster of current close loop is applied to inverter,which can advance the ability to restrain the loop current in low frequency and DC output.The experiment result confirms the validity of proposed scheme and control strategy.
